Place Value of 3
Every number consists of digits in specific positions that determine its value. The number 3 has a unique place value breakdown that helps us understand how each digit contributes to the overall number.
What Does This Mean?
In our base-10 number system, each position represents a different power of 10:
- Digits to the left of the decimal point represent whole numbers (ones, tens, hundreds, etc.)
- Digits to the right of the decimal point represent fractions (tenths, hundredths, thousandths, etc.)
- Each position's value is 10 times greater than the position to its right
Expanded Form
When we write 3 in expanded form, we show exactly how each digit contributes to the total value:

Teaching Tips
Understanding place value is fundamental to mathematics. Here are some tips for educators:
- Use physical manipulatives like base-10 blocks to represent different place values
- Practice reading large numbers by breaking them into groups of three digits
- Compare numbers with the same digits in different orders to highlight place value
- Connect place value to everyday contexts like money and measurement
